Let's evaluate f(-1)

Start with the given function


Plug in


Raise -1 to the 3rd power to get -1


Multiply -1 and -1 to get 1


Raise -1 to the 2nd power to get 1


Multiply 1 and 1 to get 1


Add 1 and 1 to get 2


Multiply 3 and -1 to get -3


Add 2 and -3 to get -1


Add -1 and 4 to get 3


--------------------------------------------------

Now let's evaluate f(0)


Start with the given function


Plug in


Raise 0 to the 3rd power to get 0


Multiply -1 and 0 to get 0


Raise 0 to the 2nd power to get 0


Multiply 1 and 0 to get 0


Add 0 and 0 to get 0


Multiply 3 and 0 to get 0


Add 0 and 0 to get 0


Add 0 and 4 to get 4



--------------------------------------------------

Now let's evaluate f(1)


Start with the given function


Plug in


Raise 1 to the 3rd power to get 1


Multiply -1 and 1 to get -1


Raise 1 to the 2nd power to get 1


Multiply 1 and 1 to get 1


Add -1 and 1 to get 0


Multiply 3 and 1 to get 3


Add 0 and 3 to get 3


Add 3 and 4 to get 7
